Challenge Problems
Push your limits with advanced challenges
An LCR circuit has an inductance of 200 mH and a capacitance of 100 nF. Calculate the resonance frequency and explain its significance in device tuning.
💡 Hint: Make sure to convert mH and nF into standard units before calculating.
A speaker system has an L of 0.5 H and a C of 20 µF. If the system experiences excessive resonance, describe the potential risks.
💡 Hint: Think about how excess current might impact the material of speakers.
